This paper is a case study on the discovery and restoration of traditional villages of Gimjae Seogangsa. The size of the building room excavated and restored is similar to ordinary houses, but the Gorae style is doedongolae, bangseonjae has nalanhigolae type of Gudeul. Even though the height difference floor, it was built to making the fire well, existed shape of Gorea is a Julgorae, The materials of agungi, gomagi, sigeundam, goraedug were constructed using large and small natural stones and mud that could easily be obtained from the surroundings. In particular, the stone used for the Goraedug was of a large size and shaped. There are no signs of repair in the two rooms of Jonegyunggae, but the floor was finished using modern cement mortar, one room was closed due to the shortage of the Gudeuljang at the time of repair, and the floor was closed with the cement mortar covering the reinforced rope and covering the slot. As the form of the Agungi seemps to be used for meeting and a guest house, so it has Hansil Agungi. Due to the seldom use of Gudeulbang, it was damaged by the moisture in the Gorae bottom Sigendam and Gomaki, the smoke was leaked have been repaired after dismantled.

Gudeul is traditional heating system of Korea that contains the much wisdom of Korean ancestors. It is a radiating heating system with a solid heat source. Recently, there has been a preference to Huangto and traditional gudeul heating in lawn houses, environment friendly house, healthy houses, and eco-houses. There is a reemphasis on the uniquely Korean traditional gudeul heating technique. Past researches have been on gudeul structure, terminology, development, and research on the efficiency of traditional gudeul has been continuously conducted. The gudeul has many parts and these parts work in close association with each other in order to successfully function as a heating system. The slightest bit of disassociation can lead to the decrease in efficiency or failure. Therefore there is a need find an exacting formula for the relationships between the parts. Therefore, an exacting survey on the sizes of gudeul need to conducted on traditional gudeul in order to preserve and develop traditional gudeul. However, there are very few surveys conducted on traditional gudeul in Designated Treasures and newly excavated sites and most of studies are conducted based on literature. In contrast to previous researches, this is an actual survey and research of the hamsil gudeul found in Mucheomdang, which it Designated Treasure No. 411.This survey was conducted by dismantling and restoring the gudeul in Mucheomdang. It was found that the goraejaejari was about 15~20cm smaller than the usual and though there was no gultukgaejari the agunggi was placed lower so that the fire went in easily, inline with the heat principle. In order to maintain and further develop traditional gudeul, gudeul survey and actual measurements must be taken at excavation sites and whenever there are restoration processes taking place in designated treasure. It is suggested that gudeul professional be included in this process because without their input it is easy to miss important aspects. If professionals are not included there is a great chance the cultural value of gudeul maybe lost forever in the near future. Gudeul is layed differently by function and region, therefore there is no one gudeul that is exactly the same, therefore, it is suggested that national, state and city government, whenever restoring or dismantling a Designated Treasure, call upon a gudeul professional. Furthermore, more traditional gudeul should be dismantled and actual measurements and surveys should be taken to collect more exacting data.

Recently there have been an increased number of people seeking to live with nature away from the polluted city. In reaction to this phenomenon there has been more an increase in interest of green sustainable architecture. Along with the interest in green sustainable architecture, there have been people who have taken interest in finding the origins of the green sustainable lifestyle, thus leading to the interest of Korean traditional architecture and its culture. This has fueled the interest and efforts in developing and restoring the traditional architecture. The interest in traditional architecture has lead to the interest in traditional ondol, which is one of the axis to Korean traditional architecture. The traditional environment friendly methods and the various green building systems have been interpreted from a modern point of view and experimented with. Therefore a variety of heating methods have been tried in preparation to the cold winter. One of those heating methods is Korea’s traditional gudeul, and through the interest of people on the gudeul a variety of gudeul has been constructed. Furthermore, educational facilities have been established to further develop, succeed and spread traditional gudeul. However, because the focus of these facilities is in the technology and preservation, it has lost focus on the traditional lifestyle. Without the understanding of traditional lifestyle, the gudeul is worthless and an uncomfortable facility. In order to truly spread the use of gudeul, the traditional lifestyle must be investigated and understood. The Korean people by laying and living on the gudeul have developed a guduel culture. Gudeul has influenced the clothing, food, and shelter, thus all aspects of life. It is a culture first then a heating method. It shines light upon the wisdom of Korean ancestors. Therefore people should not only be trained on the techniques of laying gudeul but the culture, proper maintenance and use.
